1. A job placement director claims that mean starting wage for nurses in New Mexico is $25 per hour. We suspect that this number is too opti- mistic. A random sample of 20 nurses' wages has a mean $22.6 and a standard deviation of $1.2 per hour. Is there enough evidence to reject the director's claim at a = 0.01? Also, estimate the p-value.
